I had to hurry up and shut it down and start a campaign to keep my plane and I from being destroyed. I didn't realize how much thrust it would put out since this is my first plane of this size. I had it on the kitchen table and the wife was working on paperwork across the room. It didn't take long for her papers to start flying around. Next test will be outside.
Be sure and do a full throttle run up. Like you I tried a few partial runs in shop and blew parts every where, must clean shop some milenium!
Took it to field (30 miles out) and checked on bench, again partial run up.
Taxied down run way and all looked good until I gave it 1/2 - 3/4 throttle. Motor started surging so I killed it before lift off. Verified this was happening with any current draw over 10 amps. ESC is DOA here, at least not usable as is. I tried all the timing settings, no change. My ESC had the only a toroid in throttle lead wires No amplifier or other device.
Changed out ESC (different brand) and all seems happy now. I have same ESC in Dynams Pitts with no issues in 20 flights, this one has no toroid or circuit board in any of the leads.
